PIPE WRENCH AND curries.

Lflbfifiew.

Application filed September To (/71 whom it may concern Be it known thatI, .VILLIAw N. BRUCE, a citizen of the United States, residing atHollister, in the county of San Benito and State of California, haveinvented a new and useful Pipe lVrench and Cutter, 0t which thefollowing is a specification.

The present invention relates to pipe wrenches and cutters, and aims toprovide a novel and improved device of that character.

It is the object of the invention to provide 1 pipe wrench ot the chaintype so constructed that the wrench may be employed upon various sizesof pipes or con "alent objects with equal. success and propriety, thehandle or lever having novel means for the adjustable engagement of thechain, and a pipe-engaging member connecting one end of the chain andthe end of the handle or lever, said member being adapted to bearagainst the pipe when the device is used as a wrench, and having acutter to sever the pipe when the device is used as a pipe cutter. Inother words. interchangeable elements are employed tor crmnecting thehandle or lever and chain, one otsaid elements being adapted for usewhen the device is employed as a wrench, the other element being adaptedfor use when the device is employed as a pipe cutter.

It is also within the scope of the invention to provide a device of thecharacter specified which is exceedingly simple, light, strong andinexpensive in construction. and which is durable, serviceable,practical. ellicient and convenient in use.

llith the foregoing and other objects in view which will app air as thedescription proceeds, the invention resides in the combination andarrangen'ient of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit ot theinvention.

The invention is illustrated in the panying drawing, wherein Figure l isa side elevation of the device used as a wrench, a portion of the handleor lever being broken away. Figs. 2, 3 and r are enlarged sectionaldetails taken on the lines i i 3-3 and il-, respectively, ot ig. 1. log.5 an enlarged inside view of one arm of the fork.

side elevation of the device used as a pine cutter, a portion of thehandle or lever being broken away. Fig. 7 is an enlarged perspectiveview of the cutting blade employed when the device is used as a pipecutter.

In carrying out the invention, tl are is employed a handle or lever l ofany suitable length, and provided at one end with a fork 2, the arms orprongs of which upon their inner or adjacent sides and adjacent theirtree ends with bosses or abutments 3 projecting toward and facing oneanother. The free ends of the fork arms are provided with apertureswhich also extend through the bosses 3, and the inner or. adjacent sidesof the fork arms are also provided with step portions 5 between thebosses 3 portions of said fork arms, the faces of the portions 5 beingdisposed in planes between the planes in which the faces of the bosses'3 and the inner sides of the fork arms lie. The portions 5 are eachprovided with a pair of opposite recesses 6 whose remote walls are flushwith the inner sides of the fork arms, and said recesses provide lugs Ttherebetween.

A. curved shoe 8 adapted to rest against or bear upon the pipe orequivalent object is provided between its edges with an out standingflange 9 one end of which is disposed between the bosses ii. A bolt orpivot ielement 10 is engaged through the bosses 3 and flange 9, and oneend of a chain ll is pivotallv anchored to the other end of the flange9, said member 8 serving to connect the. respective ends of the chainand lever. This member 8 is of T-shaped cross section.

The chain ll. embodies the. pairs of outer links 12, and pairs of innerlinks 13, the links being of pandurit'orm contour, and having their endsoverlapped and pivotally connected by means of rivets or pins I l whichhave their ends protruding. The pair of links 12 at one end of theclrain straddle the. respective end of the flange 9 and are pivotedthereto by means of a. bolt or pivot element if). The tree portion ofthe chain is adapted to pass snugly through the fork,

the ends of the rivets or pins l-l being adapted to snugly engage theinner or adpicent sides of the Fork arms.

In using the device as a pipewrench, after the member 8 is placedagainst the pipe, the. chain is passed around the pipe and the tree.portion of the chain is then pushed through are provided,

about the pipe whereby the pipe will be gripped to thus rotate or turnwith the lever. By swinging the lever toward the left, as seen in Fig.1,the chain can again be released and moved upon the pipe to enable a newhold to be obtained. The chain, al-

though it can effectively grip the pipe, is not liable to cut, crush orotherwise injure the pipe. The chain 11 may be adjusted readily relativeto the lever 1 for accommodating various diameters of pipes, and thelinks of the chain fit snugly between the portions 5, as seen in Fig. 2;

When the device is used as a pipe cutter, the member 8 is replaced by alink 9 having a lobe-shaped cutter blade 8 whose edge is sharpened. Theblade 8 is located adjacent one end of the link 9, and said end of thelink is adapted to pivotally engage the bolt 10 between the bosses 3,while the respective end of the chain 11 is connected by means of thebolt 15 to the other end of the link 9. Then, when lever is manipulated,the cutter blade 8 may be forcibly thrust through the walls of the pipe,and by oscillating the lever and shifting the chain around the pipe, thepipe can be cut by a single revolution of the device around the pipe.

The members 8 and 8' can be used interchangeably for connecting thelever and chain, to enable the device to be used either as a pipe wrenchor pipe cutter.

can be reversed, so. that the lever can'loe.

used in either position. I

Having thus described the invention, What is claimed as new is:

1. Ina device of the character described, a lever, a chain, the leverhaving means for the adjustable engagement of the chain, and alinkconnecting the chain and lever and having a cutter blade projectingtherefrom to cut the pipe to which the chain is applied.

2. In a device of the character described, a lever having a fork at oneend whose arms are provided at their free ends with bosses projectingtoward one another, the adjacent sides of the fork arms having stepportions between said bosses and'body portions of the arms, a pivotelement engaged through said bosses, and a chain having one endpivotally anchored to said pivot element, the chain embodying links andpins pivotally connecting them, the pins having protruding ends, andsaid step portions of the fork arms having recesses for receiving theprotruding ends of said pins and providing lugs between said recesscsfor the engagement of said pins.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.

WILLIAM NELSON BRUCE.
